Impeovement in type sepaeatoes



@einen tet @stmt @Hire IMPROVEMENT IN TYPE SBPARATORS.

Y SPECIFICATION- TO ALL WHOM I'.I MAY CONCERN:

Be it known that I, ELBER VAN GIBSON, of the city of Newark, in the vcounty of Essex, and State of New Jersey, have invented certain improvements in Apparatus for Separating Type, or that part of the machine for distributing printing type which feeds the type singly to the distributor; and I do hereby declare the following to be a full and exact description of the same, reference being herein had to the drawin i pany this specification and which make part of the same:

The nature of my improvement consists in the use of spring levers, of peculiar construction and operation, for detachingthe type from eachother when gummed together by use, and for keeping the type from bouncing in their passage; and also in a combination of levers and slides, so operated as to keep the type in the required position while moving them to the place of delivery to the rotating distributor. In the drawings,

Figure 1 is a perspective view of the separator.

Figure 2 is a representation of the spring levers in full size.

Figure 3 shows vthe cam and slide, with the separating point attached, which moves the type singly away from the column of type.

Figure 4 shows a hinged lever or spring, provided for keeping theitype from turning in their descent, and

Figure 5 represents the cam pin and lever for moving the type from the separator to the rotating distributor.

The same letters refer to the same part in each figure. v

The column of type from the form are placed in the channel a, and back of them is a slide b, that, by means of a spring, or of a cord and weight, presses the column against the stop c, in front of the separator d.

The end of the column of type next the stop is held to the` side of the channel, a, by being pressed by the spring levers e.

gs that accomihe ends of the levers are graduated to varied lengths, to adapt them to the various thicknesses in the types. The end of the top lever is placed just thethickness of a piece of metal technically termed a haii1 space from the end of the stop c. This allows the hair space to be shoved from the column oftypebythe separator d, without moving any of the spring levers, but also makes the top lever press upon the thinnest of the letter-type. The hair space, thus unguarded, drops into a pi-box, while the thin letter-type is stayed in its proper position in descending by the top spring lever and by the hinged lever'spring g.

Motion is given to the separator, d, by the cam, 7L, on the main shaft, z'; the cam impinges against the wheel, j, on the slide le, giving two forward motions to the separator at every revolution of the shaft, i; the slide, c, is returned back by the spring, l.

The ends of the levers, e, are only so much shorter on the bottom one than the top one as to have the lower one just reach on to the thickest of the capitals, the other two between touching vthe thinner types. I do not confine myself to any particular number of spring levers, nor to having detached springs to levers, as ends on the springs can do the same-work. I prefer the detached springs and levers.

The out end of the top lever is so formed as to givle` to each type a slight turn as it leaves the one behind it, insuring such a separation as to make it sure to drop away from the others. Its point is slightly curved or bevelled, and an end is made to project through the side of the channel, in which isa pin, m, to insure the exact required position of the bevel point after it has been pressed back by the moving type.

A slide, n, moved by the lever, 0, and the cam, p, on the main shaft, z', has hupon its end a bent stand, r, with a hinge on its top. To this hinge is suspended the spring, g, that is guided and has a receded motion pro- -vided for in the clasp, s, attached to the bent stand, r. ,The lower end of g reaches down just so far as to allow a type standing on its end to passbeneath it, for the purpose of keeping the type from turning in its descent. The slide, n, `comes forward just previous to the forward motion' of the separator d, advancing suiiciently to bring apressure on the type as it is moved out from the column, retreating as the separator retreats; and as .the spring. issuspended on a hinge, with a slight weight on its bent back, the lower end is continued in its pressure, which is very slight when the pressure behind, from the `end of the slide, n, is withdrawn, and only `the forward pressure of the light metal remains, being needed to keep the type from turning or bouncing out in its descent into the box, t, preparatory to its being pushed forward by the under lever, uf that receives motion by the cam pins, v, on the lower end of the main shaft, z'.

When pushed forward by the lever, u, the' type descends to the rotating distributor, w, and is carried -and deposited thereby in its proper case.

Motion is given to the whole by a cord or belt upon the pulley on the top of the main shaft, z'. What I claim as my improvement, and desire to secure by Letters Patent of the United-States, is' 1. The use of the springs or spring levers e, and thel spring g, constructed, arranged, and-operated in the manner and for the-purpose specified.

2. .Also each cam and lever shown and described when used in combination with the springs e and g, substantially in the manner and for the'purpose hereinabove set forth.
